Update 3.9 broke my sliders

I’ve encountered an issue on https://airportrevenuenews.com, since the 3.9 update.

The sliders in the NEWS FLASH and PUBLICATION sections slide left for a second, but then just jump back to their initial position, instead of rotating through.

I started with this company after the site was built (they outsourced it to India), so I’m still trying to figure out how/why they did things and the code is pretty messy. I’ve been digging around in the php files and this is what I’ve found:

For the “Publication” section, it appears they have used the Carousel Horizontal Content Slider plugin, but instead of seeing that under “Plugins” in WP, I see it under settings and there isn’t much to do in there.

For the “News Flash” section, they went with a jQuery bxSlider.

Neither of these are really “plugins” (I don’t think) and everything was working just fine yesterday, before we updated.

I’ll admit, jQuery is definitely not a strong point of mine and I haven’t done much with WP in a while, so maybe I am missing something, but I know for a fact that the only variable in this equation is the new update.

I would like to fix this on my own, instead of telling the boss he’s gonna have to send it back to India.

Thanks!
